Yeah, I’ve been fiddling around with a new Princess Smart Fan all day, and not been able to get mqtt to work. I have managed to divert all calls to *.homewizard.com and *.homewizardeasyonline.com to my nginx reverse proxy server, using adguard for the dns-rewrites. From there it changes the port and ip to my internal mqtt with tls, but I am getting no messages. They also seem to have changed the addresses as well, as I never saw a call to m.cloud… (plenty to app-ws/provisioning/bridge/mailing/cloud.homewizard.com and 0/1.homewizard.pool.ntp.org). I did test my network by connecting to cloud.homewizard.com using port 443 and tls turned on, and it connected directly to my internal mqtt server.
Maybe there’s some handshake, new authentication or change of urls we aren’t privy to. Although the alexa integration works great for now, very responsive and even oscillates the fan now. Just would have been nice to at least have some security in case homewizard/princess disappears.
Fingers crossed someone can come up with some suggestions.
